Die Erfindung betrifft eine Bahn zum Einsatz im Baubereich, mit wenigstens einem lediglich am Außenrand der Bahn vorgesehenen Befestigungsabschnitt zum Verkleben der Bahn mit einem Untergrund oder zum Verkleben mit einer weiteren Bahn.The invention relates to a track for use in the construction sector, with at least one fastening section provided only on the outer edge of the track for bonding the track to a substrate or for bonding to another track.

Im Baubereich eingesetzte Bahnen müssen miteinander oder mit anderen Materialien bzw. Untergründen verklebt werden. Bei den im Baubereich eingesetzten Bahnen kann es sich beispielsweise um Unterspannbahnen, Unterdeckbahnen, Schalungsbahnen und Fensteranschlussstreifen handeln, die im Außenbereich von Steildächern verwendet werden. Im Innenbereich von Steildächern kommen Windsperren, Dampfsperren, Dampfbremsen und Fensteranschlussstreifen zum Einsatz. Bei Flachdächern werden Dichtungsbahnen, Dampfsperren und Dampfbremsen eingesetzt. Fassadenbahnen, Housewraps und Fensteranschlussstreifen werden im Fassadenbereich benötigt. Darüber hinaus werden Dichtungsbahnen und Mauerwerkssperren bei Grundmauern und Grundplatten eingesetzt. Die im Dach- oder Fassadenbereich eingesetzten Bahnen werden luft- und winddicht miteinander verbunden und sollen die Wasser- und Luftdichtigkeit gewährleisten. Die im Bereich von Grundmauern und Grundplatten eingesetzten Bahnen sollen dagegen im Wesentlichen die Wasserdichtigkeit sicherstellen.Lanes used in the construction sector must be glued together or with other materials or substrates. The webs used in the construction sector may, for example, be underlays, underlay webs, formwork webs and window connection strips, which are used outdoors by pitched roofs. In the interior of pitched roofs, wind barriers, vapor barriers, vapor barriers and window connection strips are used. For flat roofs geomembranes, vapor barriers and vapor barriers are used. Facade membranes, housewraps and window connection strips are required in the façade area. In addition, geomembranes and masonry barriers are used on foundation walls and base plates. The membranes used in the roof or façade area are connected to each other air- and wind-tight and are intended to ensure water and airtightness. By contrast, the webs used in the area of foundation walls and base plates are intended to ensure essentially water-tightness.

Um die vorgenannten Bahnen miteinander oder mit einem Untergrund zu verbinden, können Klebebänder eingesetzt werden. Darüber hinaus können die Bahnen als solche eine Klebstoffbeschichtung aufweisen, die das Verkleben mit einem Untergrund oder mit einer weiteren Bahn ermöglicht. Selbstklebend ausgerüstete Bahnen können eine Klebstoffbeschichtung einseitig oder beidseitig aufweisen. Bei beidseitiger Klebstoffbeschichtung kann die Klebstoffschicht einer Bahn mit der Klebstoffschicht einer gegenüberliegenden Bahn verklebt werden, um einen Verbund der Bahnen sicherzustellen.To connect the aforementioned webs with each other or with a substrate, adhesive tapes can be used. In addition, the webs may as such have an adhesive coating which allows bonding to a substrate or to another web. Self-adhesive webs may have an adhesive coating on one or both sides. For double-sided adhesive coating, the adhesive layer of a web can be bonded to the adhesive layer of an opposite web to ensure a composite of the webs.

Die aus dem Stand der Technik bekannten selbstklebend ausgerüsteten Bahnen oder die zum Verkleben der Bahnen eingesetzten Klebebänder weisen eine vollflächige Beschichtung mit einem Klebstoff auf, um eine Verklebung der Bahnen mit hoher Festigkeit und ausreichender Dichtheit bzw. Dichtigkeit zu gewährleisten. Darüber hinaus muss eine vergleichsweise große Klebstoffmenge aufgetragen werden, um eine luft- bzw. winddichte Verbindung der Bahnen mit dem Untergrund oder miteinander und/oder die Wasserdichtigkeit sicherzustellen. Dies gilt insbesondere dann, wenn die Bahnen mit Oberflächen verklebt werden sollen, die hydrophobiert, verschmutzt, nass oder in anderer Art und Weise für die Verklebung wenig geeignet sind. Weiterhin weisen die bekannten Bahnen in der Regel keine glatten Oberflächen auf, so dass ein Teil des Klebers beim Verkleben der Bahnen in die Oberfläche eindringt und an der Ausbildung einer Klebeverbindung zwischen der Bahn und dem Untergrund oder einer weiteren Bahn nicht beteiligt ist. Dies gilt insbesondere bei Bahnen mit faserigen Oberflächen.The self-adhesive webs known from the prior art or the adhesive tapes used for bonding the webs have a full surface Coating with an adhesive to ensure bonding of the webs with high strength and sufficient tightness or tightness. In addition, a comparatively large amount of adhesive must be applied in order to ensure an air- or windproof connection of the webs to the substrate or to one another and / or the watertightness. This is especially true if the webs are to be glued to surfaces that are hydrophobic, dirty, wet or otherwise unsuitable for bonding. Furthermore, the known webs generally have no smooth surfaces, so that a part of the adhesive penetrates into the surface during the bonding of the webs and is not involved in the formation of an adhesive bond between the web and the substrate or another web. This applies in particular to webs with fibrous surfaces.

Sollen zwei Bahnen mit beidseitigem Klebstoffauftrag miteinander verklebt werden, besteht im Übrigen das Problem, dass die Bahnen sehr genau ausgerichtet werden müssen, um die Verklebungsbereiche zumindest überwiegend miteinander zur Deckung zu bringen.Incidentally, if two webs are to be glued together with application of adhesive on both sides, there is the problem that the webs have to be aligned very precisely in order to at least predominantly coincide with one another the bond areas.

Aus der DE 101 28 078 A1 geht bereits eine Bahn der eingangs genannten Art hervor. Die bekannte Dichtungsbahn weist Befestigungsabschnitte auf, bei denen Dichtkleberzonen vorgesehen sein können, die durch einen klebstofffreien Bereich voneinander getrennt sind. An sich geht es bei diesem Stand der Technik darum, Dichtungsbahnen bereit zu stellen, die auch im Fassadenbereich eine dauerhafte, allen Witterungs- und Umwelteinflüssen widerstehende Befestigung auf und Abdichtung zu allen üblichen Bauwerksuntergründen und untereinander bei schneller, sauberer und einfacher Verlegung ohne zusätzlichen an der Verlegestelle von außen einzubringenden Kleber zu gewährleisten. Zur Lösung dieser Aufgabe ist dort vorgesehen, dass zur Befestigung der Dichtungsbahn am Bauwerksuntergrund oder an der vorherigen Dichtungsbahn einerseits und zur Abdichtung am Bauwerksuntergrund oder zur vorherigen Dichtungsbahn andererseits unterschiedliche Kleber, nämlich ein Dichtkleber und ein Befestigungskleber, verwendet werden. Bei der bekannten Bahn sind außenseitig jeweils nur auf einer Seite der Bahn die Befestigungsabschnitte vorgesehen. Von Nachteil ist, dass sich beim Stand der Technik nicht immer eine hinreichende Dichtigkeit in der Dichtungsbahnebene erreichen lässt.From the DE 101 28 078 A1 is already a train of the type mentioned above. The known geomembrane has attachment portions in which sealing adhesive zones may be provided which are separated from each other by an adhesive-free region. In itself, it is in this state of the art to provide geomembranes that also in the façade area a permanent, all weather and environmental influences resistant attachment and sealing to all common building substrates and each other in faster, cleaner and easier installation without additional to the Laying of externally applied adhesive to ensure. To solve this problem, there is provided that for the attachment of the geomembrane on the building surface or on the previous geomembrane on the one hand and for sealing the building surface or the previous geomembrane different glue, namely a sealing adhesive and a fixing adhesive, are used. In the known track, the fastening sections are provided on the outside only on one side of the web. The disadvantage is that in the prior art can not always achieve a sufficient tightness in the sealing layer level.

Aus der DE 200 05 974 U1 und DE 200 12 227 U1 gehen jeweils Dachbahnen hervor, die unterseitig mit einer Klebeschicht versehen sind.From the DE 200 05 974 U1 and DE 200 12 227 U1 go each roofing out, which are provided on the underside with an adhesive layer.

Aus der US 2002/090496 A1 sind Bahnen und Klebestreifen mit wieder ablösbarem Klebstoff bekannt. Bei einer Ausführungsform (Fig. 3 (a)) ist auf der gesamten Oberseite der Bahn ein streifenförmiger Verklebungsbereich vorgesehen, während auf der gesamten Unterseite der Bahn ein weiterer streifenförmiger Verklebungsbereich vorgesehen ist.From the US 2002/090496 A1 are known webs and adhesive strips with removable adhesive. In one embodiment (Figure 3 (a)), a strip-shaped bonding area is provided on the entire upper side of the web, while a further strip-shaped bonding area is provided on the entire underside of the web.

Aus der DE 102 01 152 A1 geht bereits eine ein- oder mehrlagige Vlies- oder Folienbahn sowie deren Verlegung für die Dämmung von Gebäuden hervor. Die bekannte Bahn weist Klebeflächen jeweils auf gegenüberliegenden Seiten der Bahn an gegenüberliegenden Rändern auf, wobei eine Verklebung nur in Verbindung mit Flächen gleicher Beschichtung erfolgt. Bei den Klebeflächen handelt es sich jeweils um vollflächige Klebestreifen. Bei der bekannten Bahn wird ein solcher Klebstoff verwendet, bei dem sich eine Klebewirkung nur dann ergibt, wenn er mit einem weiteren Klebestreifen einer anderen Bahn in Verbindung kommt. Aufgrund dieser Klebstoffwahl sind bei der bekannten Bahn auch keine Schutzfolien über den Klebeflächen erforderlich.From the DE 102 01 152 A1 is already a single- or multi-layer nonwoven or film web and their installation for the insulation of buildings. The known web has adhesive surfaces on opposite sides of the web at opposite edges, wherein bonding takes place only in conjunction with surfaces of the same coating. The adhesive surfaces are each full-surface adhesive strips. In the known web, such an adhesive is used in which an adhesive effect only results when it comes into contact with another adhesive strip of another web. Due to this choice of adhesive no protective films on the adhesive surfaces are required in the known web.

Aufgabe der vorliegenden Erfindung ist es, eine Bahn der eingangs genannten Art zur Verfügung zu stellen, die in einfacher Weise verlegt und verklebt werden kann, kostengünstig ist und wobei die durch Verkleben erhältliche Klebeverbindung eine hohe Schälfestigkeit und Dichtheit bzw. Dichtigkeit aufweisen soll.Object of the present invention is to provide a web of the type mentioned above, which can be installed and glued in a simple manner, is inexpensive and wherein the adhesive bond obtainable by adhesive bonding should have a high peel strength and tightness or impermeability.

Die vorgenannte Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Der Grundgedanke der Erfindung ist darin zu sehen, dass der Befestigungsabschnitt nur an bestimmten Bereichen mit einem Klebstoff beschichtet wird. Bei Schälversuchen konnte überraschenderweise festgestellt werden, dass sich auch bei nur teilflächiger Klebstoffbeschichtung im Befestigungsabschnitt eine vergleichbar hohe Schälfestigkeit ergibt wie bei Bahnen, die eine vollflächige Beschichtung des Befestigungsabschnitts mit einem Klebstoff aufweisen. In Schälmessungen konnten beispielsweise an einem 50 mm breiten streifenförmigen Befestigungsabschnitt mit einer Prüfgeschwindigkeit von 100 mm/min Festigkeiten von 3 bis 200 N, insbesondere von 7 bis 100 N, weiter insbesondere von 10 bis 70 N, erreicht werden. Aufgrund der erfindungsgemäßen teilflächigen Beschichtung des Befestigungsabschnitts kann Klebstoff eingespart werden, was zu einem Absinken der Herstellungskosten der erfindungsgemäßen Bahn beiträgt, Es versteht sich, dass die vorangegangenen Ausführungen in derselben Weise auch für ein Klebeband mit einem Befestigungsabschnitt gelten, wobei der Befestigungsabschnitt lediglich teilflächig mit einem Klebstoff beschichtet ist und wobei Verklebungsbereiche durch klebstofffreie Bereiche des Befestigungsabschnitts voneinander getrennt sind.The aforementioned object is achieved by the features of claim 1. The basic idea of the invention can be seen in the fact that the fastening section is coated with an adhesive only at certain areas. In peel tests, it was surprisingly found that a comparatively high peel strength results even in the case of only partial adhesive coating in the attachment section, as in the case of webs which have a full-surface coating of the attachment section with an adhesive. In peel measurements, it was possible, for example, to achieve strengths of 3 to 200 N, in particular 7 to 100 N, more particularly 10 to 70 N, on a 50 mm wide strip-shaped attachment section with a test speed of 100 mm / min. Due to the inventive partial coating of the attachment portion adhesive can be saved It goes without saying that the preceding statements also apply in the same way to an adhesive tape having a fastening section, wherein the fastening section is only partially coated with an adhesive and bonding regions are protected by adhesive-free regions of the adhesive Attachment section are separated.

Zum Schutz des Befestigungsabschnitts ist dieser im Nicht-Gebrauchszustand mit einer abziehbaren Schutzfolie beklebt, die vor der Verklebung der Bahn abgezogen werden muss.To protect the mounting portion of this is stuck in the non-use state with a peelable protective film, which must be deducted before bonding the web.

Um eine Luft-/Winddichtheit und Wasserdichtigkeit zu gewährleisten, muß mindestens ein durchgängiger Pfad der Verklebung beim Verkleben der Bahn mit dem Untergrund oder der Bahnen miteinander erhalten werden. Um eine hohe Dichtheit bzw. Dichtigkeit sicherzustellen, können insbesondere auch zwei durchgängige Pfade der Verklebung vorgesehen sein. Bei einer bevorzugten Ausführungsform der Erfindung ist daher vorgesehen, dass die Verklebungsbereiche derart gebildet bzw. angeordnet sind, dass sich beim Verkleben der Bahn mit dem Untergrund oder mit einer weiteren Bahn über die gesamte Länge und/oder die gesamte Breite der Bahn eine im wesentlichen unterbrechungslose Klebeverbindung zwischen wenigstens einem Verklebungsbereich und dem Untergrund oder der weiteren Bahn ausbildet. Die Formulierung "im wesentlichen unterbrechungslos" stellt in diesem Zusammenhang klar, dass es für eine ausreichende Dichtheit bzw. Dichtigkeit unter Umständen ausreicht, wenn der Verklebungsbereich im wesentlichen vollständig mit dem Untergrund oder der weiteren Bahn verklebt ist und nur ein Abschnitt oder wenige Abschnitte des Verklebungsbereiches über eine kurze Länge von beispielsweise einigen Zentimetern nicht mit dem Untergrund oder der weiteren Bahn verklebt ist bzw. sind. Von Vorteil ist jedoch, wenn sich eine vollständig unterbrechungslose Klebeverbindung ausbildet.In order to ensure air / wind tightness and watertightness, at least one continuous path of bonding must be obtained when bonding the web to the substrate or webs. In order to ensure a high tightness or tightness, in particular, two continuous paths of the bond can be provided. In a preferred embodiment of the invention it is therefore provided that the bonding areas are formed or arranged such that when bonding the web to the ground or with another web over the entire length and / or the entire width of the web a substantially uninterrupted Adhesive bond between at least one bonding area and the substrate or the further path is formed. The wording "substantially uninterrupted" in this context makes it clear that under certain circumstances it is sufficient for sufficient tightness or imperviousness if the bond area is essentially completely bonded to the substrate or the further web and only a portion or a few portions of the bond area over a short length of, for example, a few centimeters is not glued to the ground or the further path or are. It is advantageous, however, if a completely uninterrupted adhesive bond is formed.

Der Befestigungsabschnitt kann sich vorzugsweise in Längsrichtung der Bahn streifenförmig an einem oder beiden Außenrändern und/oder an der Ober-und/oder der Unterseite der Bahn erstrecken, vorzugsweise über die gesamte Länge der Bahn. Grundsätzlich ist es natürlich auch möglich, dass sich der Befestigungsabschnitt quer zur Längsrichtung der Bahn vorzugsweise über die gesamte Breite unter- und/oder oberseitig der Bahn erstreckt.The attachment portion may preferably extend in the longitudinal direction of the web in strip form at one or both outer edges and / or at the top and / or bottom of the web, preferably over the entire length of the web. In principle, it is of course also possible for the attachment section to extend transversely to the longitudinal direction of the web, preferably over the entire width, underneath and / or on top of the web.

Nachfolgend werden vorteilhafte Ausgestaltungen der Erfindung am Beispiel einer erfindungsgemäßen Bahn im Einzelnen erläutert. Es versteht sich, dass die nachfolgend genannten Merkmale auch bei einem Klebeband der erfindungsgemäßen Art von Vorteil und vorgesehen sein können, auch wenn dies im einzelnen nicht beschrieben wird.In the following, advantageous embodiments of the invention will be explained in detail using the example of a web according to the invention. It is understood that the features mentioned below can also be advantageous and provided for an adhesive tape of the type according to the invention, even if this is not described in detail.

Vorzugsweise können sich zu dem vorgenannten Zweck die Verklebungsbereiche der Bahn unterbrechungslos über die gesamte Bahnlänge und/oder die gesamte Bahnbreite erstrecken. Durch geeignete Anordnung der Verklebungsbereiche, deren Breite und Form sowie durch geeignete Festlegung der Auftragsdicke kann bei geeigneter Auswahl eines Klebstoffs eine luftdichte und/oder wasserdichte Klebeverbindung sichergestellt werden.Preferably, for the above purpose, the bond areas of the web may extend uninterrupted over the entire web length and / or the entire web width. By suitable arrangement of the bonding areas, their width and shape as well as by suitable definition of the application thickness can be ensured with a suitable selection of an adhesive an airtight and / or waterproof adhesive connection.

Zum leichten Verkleben der Bahn mit einer weiteren Bahn kann auf der Oberseite und auf der Unterseite der Bahn jeweils wenigstens ein Befestigungsabschnitt vorgesehen sein. Es ist möglich, dass eine Bahn auf beiden Seiten eine teilflächige Klebstoffbeschichtung gemäß der zuerst beschriebenen Ausführungsform der Erfindung aufweist. Ebenso gut ist es möglich, dass auf der einen Seite eine teilflächige Klebstoffbeschichtung und auf der anderen Seite eine vollflächige Klebstoffbeschichtung vorgesehen ist. Beispielsweise kann weiter vorgesehen sein, dass ein auf der Oberseite vorgesehener Befestigungsabschnitt eine andere Breite aufweist als ein auf der Unterseite der Bahn vorgesehener Befestigungsabschnitt. Hier ist es möglich, dass ein vergleichsweise breiter Befestigungsabschnitt auf der Oberseite einer Bahn mit einem vergleichsweise schmaleren Befestigungsabschnitt auf der Unterseite einer weiteren Bahn verklebt wird, wobei die miteinander verklebten Bahnen zumindest im Bereich der Befestigungsabschnitte überlappen. Durch unterschiedliche Breiten der Befestigungsabschnitte ist es nicht notwendig, die Bahnen sehr genau aufeinander auszurichten, um die Befestigungsabschnitte zumindest überwiegend miteinander zur Deckung zu bringen. Auch bei nicht genauer Ausrichtung der Bahnen bzw. der Befestigungsabschnitte kann eine luft-/winddichte Klebeverbindung und eine hohe Wasserdichtigkeit bei ausreichender Festigkeit der Klebeverbindung gewährleistet werden.For easy bonding of the web to another web, at least one fastening section can be provided on the upper side and on the lower side of the web. It is possible that a web has on both sides a partial adhesive coating according to the first described embodiment of the invention. It is equally possible for a partial adhesive coating to be provided on one side and a full-surface adhesive coating on the other side. For example, it can further be provided that a fastening section provided on the upper side has a different width than a fastening section provided on the lower side of the web. Here, it is possible for a comparatively wide fastening section on the upper side of a web to be glued to a comparatively narrower fastening section on the underside of a further web, wherein the webs glued together overlap at least in the region of the fastening sections. Due to different widths of the attachment portions, it is not necessary to align the tracks very closely to each other to bring the attachment portions at least predominantly to cover. Even if the webs or fastening sections are not precisely aligned, an air / windproof adhesive bond and high water tightness can be ensured with sufficient strength of the adhesive bond.

Vorzugsweise sind die Verklebungsbereiche in regelmäßigen Abständen zueinander bzw. mit einem definierten Muster angeordnet. Beispielsweise können Verklebungsbereiche und nicht-verklebte Bereiche des Befestigungsabschnitts alternierend nebeneinander vorgesehen sein. Das gleiche gilt selbstverständlich auch für Verklebungsbereiche mit unterschiedlicher Auftragsdicke der Klebstoffbeschichtung, die ebenfalls alternierend nebeneinander angeordnet sein können. Dadurch wird das Verkleben der Bahnen insbesondere miteinander vereinfacht und eine hohe Festigkeit und Dichtheit bzw. Dichtigkeit der Klebeverbindung sichergestellt.Preferably, the bonding areas are arranged at regular intervals from each other or with a defined pattern. For example, bonding areas and non-bonded areas of the attachment portion be provided alternately side by side. Of course, the same applies to bonding areas with different application thickness of the adhesive coating, which can also be arranged alternately next to each other. As a result, the bonding of the webs is in particular simplified together and ensures high strength and tightness or tightness of the adhesive bond.

Der Verklebungsbereich kann linienförmig ausgebildet sein, wobei, vorzugsweise, der Befestigungsabschnitt eine Mehrzahl von geraden oder wellenartig nebeneinander liegenden linienförmigen Verklebungsbereichen aufweisen kann. Beispielsweise können gerade linienförmige Verklebungsbereiche nebeneinander liegend vorgesehen sein, wobei sich die Verklebungsbereiche über die gesamte Länge der Bahn erstrecken und von nicht-verklebten Bereichen des Befestigungsabschnitts quer zur Längsrichtung voneinander getrennt sein können. Bei der zuvor beschriebenen Ausführungsform erstrecken sich die Verklebungsbereiche der Bahn unterbrechungslos über die gesamte Bahnlänge. Es kann jedoch auch sein, dass die Verklebungsbereiche Unterbrechungen aufweisen und quer zur Längsrichtung versetzt zueinander angeordnet sind, so dass insgesamt wieder eine luft-/winddichte Verklebung bzw. die Wasserdichtigkeit der Klebeverbindung sichergestellt werden kann. Ebenso gut ist es möglich, dass der Befestigungsabschnitt netzartig mit dem Klebstoff beschichtet ist. Auch hier ergibt sich aufgrund der Netzstrukturen ein durchgängiger Pfad der Verklebung, der die Luft-/Winddichtheit und Wasserdichtigkeit gewährleistet. In diesem Zusammenhang können die Verklebungsbereiche eine Breite von 0,5 bis 30 mm, vorzugsweise von 1 bis 15 mm, insbesondere von 1,5 bis 8 mm, aufweisen.The bonding area may be linear, wherein, preferably, the attachment portion may have a plurality of straight or wave-like juxtaposed linear bonding areas. For example, straight line-shaped bonding areas can be provided next to one another, the bonding areas extending over the entire length of the web and being able to be separated from non-bonded areas of the fastening section transversely to the longitudinal direction. In the embodiment described above, the bond areas of the web extend uninterruptedly over the entire length of the web. However, it can also be that the bonding areas have interruptions and are arranged offset from one another transversely to the longitudinal direction, so that overall an air / windproof bonding or the water-tightness of the adhesive bond can be ensured again. It is equally possible that the attachment portion is net-coated with the adhesive. Again, due to the network structures results in a continuous path of the bond, which ensures the air / windproofness and water resistance. In this connection, the bonding areas may have a width of 0.5 to 30 mm, preferably of 1 to 15 mm, in particular of 1.5 to 8 mm.

Sind linienförmige Verklebungsbereiche vorgesehen, können alle Verklebungsbereiche die gleiche Breite aufweisen. Es versteht sich, dass auch Verklebungsbereiche mit unterschiedlicher Breite vorgesehen sein können, insbesondere auf unterschiedlichen Außenseiten der Bahn. Die Breite der linienförmigen Verklebungsbereiche hängt von deren Anzahl pro Befestigungsabschnitt und der Auftragtechnik des Klebstoffs ab, wobei der Klebstoffauftrag mittels (Auslauf-)Düsen, Walzen oder Sprühdüsen erfolgen kann. Auch ist es möglich, den Klebstoff durch Rotationssprühen oder Spinnblasen (melt blown) auf den Befestigungsabschnitt aufzutragen.If line-shaped bonding areas are provided, all bond areas can have the same width. It goes without saying that bonding regions with different widths can also be provided, in particular on different outer sides of the web. The width of the line-shaped bonding areas depends on their number per attachment section and the application technique of the adhesive, wherein the adhesive application can take place by means of (discharge) nozzles, rollers or spray nozzles. It is also possible to apply the adhesive by rotational spraying or meltblown (blown) on the attachment portion.

Der Befestigungsabschnitt kann jedoch auch eine Mehrzahl von spiral- oder Ωstrukturförmigen Verklebungsbereichen aufweisen. Die Spiral- oder Ω-Strukturen sind dabei derart angeordnet, dass sich beim Verkleben wiederum mindestens ein durchgängiger Pfad der Verklebung ergibt. Die Verklebungsbereiche können eine geringere Breite aufweisen, da aufgrund der Spiral- oder Ω-Struktur beim Verkleben der Bahn mit einem Untergrund oder mit einer weiteren Bahn eine Mehrzahl von durchgängigen Pfaden der Verklebung erhalten wird. Hier kann die Breite der die Spiral- oder Ω-Struktur bildenden Klebstofflinien 0,1 bis 5 mm, vorzugsweise 0,3 bis 3 mm, insbesondere 0,5 bis 2 mm betragen. Im Übrigen können auch Klebstofflinien mit unterschiedlicher Breite vorgesehen sein.However, the attachment portion may also have a plurality of spiral or Ω-structured bonding areas. The spiral or Ω structures are arranged in such a way that during bonding, in turn, at least one continuous path of the bond results. The bonding areas may have a smaller width, since, due to the spiral or Ω structure, a plurality of continuous paths of bonding are obtained when bonding the web to a substrate or to another web. Here, the width of the spiral or Ω-structure forming adhesive lines 0.1 to 5 mm, preferably 0.3 to 3 mm, in particular 0.5 to 2 mm. Incidentally, adhesive lines with different widths can also be provided.

Wird der Klebstoff faserförmig auf den Befestigungsabschnitt aufgesprüht, kann der Befestigungsabschnitt vorzugsweise randomisiert aufgetragene Klebstoffasern mit einem Durchmesser von 0,001 bis 2 mm, vorzugsweise von 0,005 bis 1 mm, insbesondere von 0,01 bis 0,5 mm, aufweisen.If the adhesive is sprayed onto the attachment section in a fibrous manner, the attachment section may preferably have randomly applied adhesive fibers having a diameter of 0.001 to 2 mm, preferably of 0.005 to 1 mm, in particular of 0.01 to 0.5 mm.

Letztlich können durch geeignete Auftragsmethoden Verklebungsbereiche in Form von geraden- oder wellenartigen Linien, netzartige Verklebungsbereiche oder spiral- oder Ω-strukturförmige Verklebungsbereiche erzeugt werden.Ultimately, bonding areas in the form of straight or wave-like lines, net-like bonding areas or spiral or Ω-structured bonding areas can be produced by suitable application methods.

Die Breite des Befestigungsabschnitts kann 5 bis 150 mm, vorzugsweise 10 bis 100 mm, insbesondere 20 bis 80 mm, betragen. Dabei kann vorgesehen sein, dass der Befestigungsabschnitt an den Längsrändern und/oder an den Querrändem der Bahn vorgesehen ist. Wie bereits darauf hingewiesen worden ist, können auf der Oberseite und auf der Unterseite der Bahn Befestigungsabschnitte mit unterschiedlicher Breite vorgesehen sein, um das Verkleben der Bahnen miteinander zu vereinfachen.The width of the fastening section may be 5 to 150 mm, preferably 10 to 100 mm, in particular 20 to 80 mm. It can be provided that the attachment portion is provided at the longitudinal edges and / or at the transverse edges of the web. As has already been pointed out, mounting portions of different widths may be provided on the top and bottom of the web to facilitate bonding of the webs together.

Das Auftragsgewicht der Klebstoffbeschichtung bezogen auf den Befestigungsabschnitt kann 5 bis 500 g/m2, vorzugsweise 20 bis 300 g/m2 insbesondere 35 bis 200 g/m2, betragen. Dadurch kann eine ausreichend feste Verklebung und eine hohe Dichtheit bzw. Dichtigkeit der Klebeverbindung sichergestellt werden.The application weight of the adhesive coating based on the attachment portion may be 5 to 500 g / m 2 , preferably 20 to 300 g / m 2, in particular 35 to 200 g / m 2 . As a result, a sufficiently strong bond and a high tightness or tightness of the adhesive bond can be ensured.

Als Kleber kommen an sich aus dem Stand der Technik bekannte Systeme wie Hotmelts, Dispersionen und lösemittelhaltige Klebstoffe oder dgl, in Betracht, die auch vernetzt sein können. Die Kleber können Additive wie zum Beispiel UV-Stabilisatoren, Antioxidantien, Flammenhemmer oder dgl, enthalten.Suitable adhesives are systems known per se from the prior art, such as hotmelts, dispersions and solvent-based adhesives or the like. which can also be networked. The adhesives may contain additives such as UV stabilizers, antioxidants, flame retardants or the like.

Der Bedeckungsgrad des Befestigungsabschnitts mit einer Klebstoffbeschichtung kann 5 bis 90%, vorzugsweise 10 bis 70%, insbesondere 20 bis 50%, jeweils bezogen auf die Gesamtfläche des Befestigungsabschnitts betragen. Bei vollflächiger Beschichtung des Befestigungsabschnitts kann dagegen vorgesehen sein, dass der Bedeckungsgrad des Befestigungsabschnitts mit Verklebungsbereichen, die eine im wesentlichen gleich höhere Auftragsdicke aufweisen, 5 bis 90%, vorzugsweise 10 bis 70%, insbesondere 20 bis 50%, jeweils bezogen auf die Gesamtfläche des Befestigungsabschnitts beträgt. Der Bedeckungsgrad bezieht sich bei der zuletzt beschriebenen Ausführungsform somit auf die Verklebungsbereiche mit höherer Auftragsdicke, die gegenüber anderen Verklebungsbereichen mit geringerer Auftragsdicke nach außen überstehen. Die gewählten Bedeckungsgrade sind ausreichend, um das Verkleben der Bahn mit einem Untergrund oder mit einer weiteren Bahn bei hoher Festigkeit der Klebeverbindung und ausreichender Dichtheit bzw. Dichtigkeit zu ermöglichen.The degree of coverage of the fastening section with an adhesive coating may be 5 to 90%, preferably 10 to 70%, in particular 20 to 50%, in each case based on the total area of the fastening section. In full-surface coating of the attachment portion, however, can be provided that the degree of coverage of the mounting portion with bonding areas having a substantially equal application thickness, 5 to 90%, preferably 10 to 70%, in particular 20 to 50%, each based on the total area of Fixing section amounts. The degree of coverage in the case of the last-described embodiment therefore relates to the bonding areas with a higher application thickness, which protrude outwards with respect to other bond areas with a lower application thickness. The chosen degrees of coverage are sufficient to allow the web to be bonded to a substrate or to another web with high strength of the adhesive bond and sufficient tightness.

Nachfolgend werden bevorzugte Ausführungsbeispiele der Erfindung beschrieben:Hereinafter, preferred embodiments of the invention will be described:

Beispiel 1example 1

Eine an sich bekannte Unterdeckbahn mit der Handelsbezeichnung Delta Vent S der Anmelderin, bestehend aus einem Verbund von 40 g/m2 PP-Vlies, 40 g/m2 mikroporöser Membran und 70g/m2 PP-Vlies, wird einseitig an einem Rand mit einem 30 mm breiten Hotmelt-Streifen mit der Handelsbezeichnung Kleiberit SK 728.6 der Firma Kleiberit beschichtet, um den Befestigungsabschnitt zu erhalten. Das Flächengewicht beträgt 150 g/m2. Der Auftrag erfolgt aus einer Breitschlitzdüse mit eingelegter Kammstruktur, so dass sechs streifenförmige Verklebungsbereiche mit jeweils einer Breite von 3 mm entstehen.A known underlayment with the trade name Delta Vent S of the applicant, consisting of a composite of 40 g / m 2 PP nonwoven, 40 g / m 2 microporous membrane and 70g / m 2 PP nonwoven, is on one side with an edge A 30 mm wide strip of hotmelt with the trade name Kleiberit SK 728.6 from Kleiberit coated to obtain the attachment section. The basis weight is 150 g / m 2 . The order is made from a slot die with inserted comb structure, so that six strip-shaped bonding areas each with a width of 3 mm are formed.

Beispiel 2Example 2

Die Bahn gemäß Beispiel 1 wird zusätzlich am anderen Rand mit einem 80 mm breiten Hotmelt-Streifen mit einem Flächengewicht von 50 g/m2 beschichtet, um den Befestigungsabschnitt zu erhalten. Dazu wird eine ähnliche, allerdings breitere Düse eingesetzt, die während des Auftrags orthogonal zum Rand der Bahn mit einer Auslenkung von 10 mm bewegt wird. Die Bahn wird unterhalb der Düse entlang bewegt. Dabei entstehen wellenartige Verklebungslinien mit einer Breite von ca. 4 mm, die beim Verkleben mit gerade verlaufenden linienförmigen Verklebungsbereichen einer anderen Bahn durchgehende Verklebungspfade bilden.The web according to Example 1 is additionally coated at the other edge with an 80 mm wide hotmelt strip with a basis weight of 50 g / m 2 in order to obtain the fastening section. This will be a similar, but wider Nozzle inserted, which is moved during the order orthogonal to the edge of the web with a deflection of 10 mm. The web is moved below the nozzle. This results in wave-like bond lines with a width of about 4 mm, which form during bonding with straight line-shaped bonding areas of another path continuous bonding paths.

In Fig. 1 ist eine Bahn 1 mit einem Befestigungsabschnitt 2 auf der Oberseite der Bahn 1 und mit einem weiteren Befestigungsabschnitt 3 auf der Unterseite der Bahn 1 dargestellt, wobei die Befestigungsabschnitte 2, 3 zum Verkleben der Bahn 1 mit einer nicht dargestellten weiteren Bahn 1 oder zum Verkleben mit einem nicht dargestellten Untergrund vorgesehen sind. Die Befestigungsabschnitte 2, 3 sind teilflächig mit einem Klebstoff beschichtet und weisen eine Mehrzahl von durch die Klebstoffbeschichtung gebildeten Verklebungsbereichen 4, 5 auf. Die Verklebungsbereiche 4, 5 erstrecken sich in Längsrichtung der Bahn 1 an den Außenrändern über die gesamte Länge der Bahn 1. Die Verklebungsbereiche 4, 5 sind als gerade Klebstofflinien ausgebildet, die durch klebstofffreie Bereiche 6, 7 voneinander getrennt sind. Dadurch kann der Klebstoffverbrauch bei der Beschichtung des Befestigungsabschnitts 2, 3 gegenüber den aus dem Stand der Technik bekannten Bahnen gesenkt werden, was zu einer deutlichen Kosteneinsparung beiträgt. Gleichwohl ist eine durchgängige Verklebung der Bahn 1 mit einem Untergrund oder mit einer weiteren Bahn möglich, wobei sich über die gesamte Bahnlänge eine luftdichte und wasserdichte Klebeverbindung mit hoher Festigkeit ausbildet.In Fig. 1 is a web 1 with a mounting portion 2 on top of the web 1 and with a further mounting portion 3 on the underside of Lane 1 shown, wherein the mounting portions 2, 3 are provided for bonding the web 1 with a further web 1, not shown, or for bonding to a substrate, not shown. The attachment sections 2, 3 are partially coated with an adhesive and have a plurality of bond areas 4, 5 formed by the adhesive coating. The bonding areas 4, 5 extend in the longitudinal direction of the web 1 at the outer edges over the entire length of the web 1. The bonding areas 4, 5 are formed as straight adhesive lines, which are separated from each other by adhesive-free areas 6, 7. As a result, the adhesive consumption in the coating of the attachment portion 2, 3 can be reduced compared to the known from the prior art webs, which contributes to a significant cost savings. However, a continuous bonding of the web 1 with a substrate or with another web is possible, forming an air-tight and waterproof adhesive bond with high strength over the entire length of the web.

Die Bahn 1 weist auf der Oberseite den Befestigungsabschnitt 2 auf, der quer zur Längsrichtung der Bahn 1 durch die beiden äußeren Verklebungsbereiche 4 begrenzt ist. Auf der Unterseite der Bahn 1 ist der Befestigungsabschnitt 3 vorgesehen, der lediglich zwei Befestigungsbereiche 5 aufweist, die durch einen klebstofffreien Bereich 7 voneinander getrennt sind. Im Ergebnis ist die Breite des auf der Oberseite der Bahn 1 vorgesehenen Befestigungsabschnitts 2 größer als die Breite des auf der Unterseite der Bahn 1 vorgesehenen Befestigungsabschnitts 3. Werden Bahnen 1 überlappend miteinander verklebt, so kommt es zur Ausbildung einer Klebeverbindung zwischen dem Befestigungsabschnitt 2 auf der Oberseite der Bahn 1 und einem Befestigungsabschnitt 3 auf der Unterseite einer weiteren Bahn 1. Die unterschiedliche Breite der Befestigungsabschnitte 2, 3 ermöglicht es, überlappende Bahnen 1 miteinander zu verkleben, ohne dass die Befestigungsabschnitte 2, 3 genau aufeinander ausgerichtet werden müssen, um eine luft- und wasserdichte Klebeverbindung mit hoher Festigkeit sicherzustellen.The web 1 has on the upper side the attachment portion 2 which is bounded transversely to the longitudinal direction of the web 1 by the two outer bonding areas 4. On the underside of the web 1 of the attachment portion 3 is provided, which has only two attachment areas 5, which are separated by an adhesive-free area 7 from each other. As a result, the width of the attachment section 2 provided on the upper side of the track 1 is greater than the width of the attachment section 3 provided on the underside of the track 1. If tracks 1 are glued together in an overlapping manner, an adhesive bond is formed between the attachment section 2 on the The top of the web 1 and a mounting portion 3 on the underside of another web 1. The different width of the mounting portions 2, 3 makes it possible to glue overlapping webs 1 together without the mounting sections 2, 3 must be aligned with each other exactly to an air To ensure - and waterproof adhesive bond with high strength.

In Fig. 1b bis Fig. 1e ist jeweils eine Draufsicht auf einen Bahnabschnitt einer erfindungsgemäßen Bahn dargestellt, wobei sich die Verklebungsbereiche 4 gemäß Fig. 1b netzartig überlagern und gemäß Fig. 1c als wellenförmig verlaufende Klebstofflinien ausgebildet sind. Gemäß Fig. 1d ist es vorgesehen, dass sich der Befestigungsabschnitt 2 über eine größere Breite auf der Oberseite der Bahn 1 erstreckt und durch Aufsprühen von Klebstofffasern erhältlich ist. Die klebstofffreien Bereiche 6 des Befestigungsabschnitts 2 werden durch die Leerräume gebildet, die beim Aufsprühen von Klebstoff Fasern auf die Oberseite der Bahn 1 entstehen. Die Größe der klebstofffreien Bereiche 6 des Befestigungsabschnitts 2 wird daher durch die Sprühparameter beim Aufsprühen der Klebstoff-Fasern festgelegt. Im Ergebnis wird der Befestigungsbereich 2 "vollflächig" mit Klebstoff-Fasern besprüht, wobei diese die Oberseite der Bahn 1 im Bereich des Befestigungsabschnitts 2 jedoch nicht vollständig bedecken. Die diskreten Bereiche der Beschichtung werden durch die einzelnen Klebstoff-Fasern selbst erzeugt. Bei der in Fig. 1e dargestellten Bahn weist der Befestigungsabschnitt 2 mehrere Verklebungsbereiche 4 auf, die ebenfalls durch Aufsprühen von Klebstofffasern erhältlich sind.In Fig. 1b to Fig. 1e in each case a plan view of a web portion of a web according to the invention is shown, wherein the bonding areas 4 according to Fig. 1b superimpose net and according to Fig. 1c are formed as wave-shaped adhesive lines. According to Fig. 1d it is provided that the attachment portion 2 over a greater width on the top of the web. 1 extends and is obtainable by spraying on adhesive fibers. The adhesive-free areas 6 of the attachment portion 2 are formed by the voids which arise when spraying adhesive fibers on the top of the web 1. The size of the adhesive-free areas 6 of the attachment portion 2 is therefore determined by the spray parameters during the spraying of the adhesive fibers. As a result, the fastening region 2 is sprayed "over the entire surface" with adhesive fibers, but these do not completely cover the upper side of the web 1 in the region of the fastening section 2. The discrete areas of the coating are produced by the individual adhesive fibers themselves. At the in Fig. 1e As shown, the attachment portion 2 has a plurality of bonding areas 4, which are also obtainable by spraying adhesive fibers.

In Fig. 2 ist eine Teil-Querschnittsansicht der Bahn 1 im Bereich des Befestigungsabschnitts 2 dargestellt. Wie sich aus Fig. 2 insbesondere ergibt, weisen alle Verklebungsbereiche 4 dieselbe Breite auf. Die klebstofffreien Bereiche 6 weisen dagegen eine größere Breite auf als die Verklebungsbereiche 4. Es ist auch möglich, dass die Verklebungsbereiche 4 und die klebstofffreien Bereiche 6 gleich breit sind.In Fig. 2 a partial cross-sectional view of the web 1 in the region of the attachment portion 2 is shown. As it turned out Fig. 2 In particular, all bonding areas 4 have the same width. On the other hand, the adhesive-free regions 6 have a greater width than the adhesive regions 4. It is also possible for the adhesive regions 4 and the adhesive-free regions 6 to have the same width.

In Fig. 3 ist eine Teil-Querschnittsansicht einer weiteren Ausführungsform einer Bahn 1 dargestellt. Die Verklebungsbereiche 8, 9 bilden einen Befestigungsabschnitt 10 zum Verkleben der Bahn 1 mit einem Untergrund oder zum Verkleben mit einer weiteren Bahn 1. Der Befestigungsabschnitt 10 ist vollflächig mit einem Klebstoff beschichtet, wobei die durch die Klebstoffbeschichtung gebildeten Verklebungsbereiche 8, 9 eine unterschiedliche Auftragsdicke der Klebstoffbeschichtung aufweisen. Dies ermöglicht das Verkleben der Bahn 1 auch mit nicht-ebenen Oberflächen bei insgesamt geringerem Klebstoffverbrauch im Vergleich zum Verkleben von solchen Bahnen, die eine Klebstoffbeschichtung mit konstanter Auftragsdicke über den gesamten Befestigungsabschnitt aufweisen.In Fig. 3 a partial cross-sectional view of another embodiment of a web 1 is shown. The bonding areas 8, 9 form a fastening portion 10 for bonding the web 1 to a substrate or for bonding to another web 1. The mounting portion 10 is coated over its entire surface with an adhesive, wherein the bonding areas 8, 9 formed by the adhesive coating have a different application thickness Have adhesive coating. This allows the bonding of the web 1 even with non-planar surfaces with an overall lower adhesive consumption compared to the bonding of such webs having a coating adhesive with a constant application thickness over the entire mounting portion.
